Precision low-energy measurements have played an important role in
uncovering the structure of the electroweak interaction. I discuss the role
which a new generation of precision measurements may play in the search for
physics beyond the Standard Model. In particular, I discuss the muon
anomalous magnetic moment, neutron and nuclear beta-decay, and
parity-violating ee and ep scattering. I argue that the information gleaned
from these studies could constrain new physics scenarios such as
supersymmetry in a manner complementary to high energy collider
measurements.
